Any operation or set of Any operation or set of
operations performed upon data, operations performed upon data,
whether or not by automatic means, whether or not by automatic means,
such as collection, recording, such as collection, recording,
organization, storage, adaptation or organization, storage, adaptation or
alteration to convert it into useful alteration to convert it into useful

4. Types of Data ProcessingTypes of Data Processing
1. Manual Data Processing1. Manual Data Processing
This method of This method of data processingdata processing involves involves
human intervention. The manual process of data human intervention. The manual process of data
entry implies many opportunities for errors, such as entry implies many opportunities for errors, such as
delays in data capture, as every single data field has delays in data capture, as every single data field has
to be keyed in manually, a high amount of operator to be keyed in manually, a high amount of operator
misprints or typos, high labor costs from the amount misprints or typos, high labor costs from the amount
of manual labor required. Manual processing also of manual labor required. Manual processing also
implies higher labor expenses in regards to spending implies higher labor expenses in regards to spending
for equipment and supplies, rent, etc.for equipment and supplies, rent, etc.

2. Mechanical Data Processing
Different calculations and processing
are performed using mechanical machines like
calculators etc. The use of mechanical machines
makes data processing easier and less time-
consuming. The chances of errors also become
far less than manual data processing.

3. Electronic Data Processing
EDP an infrequently used term for EDP an infrequently used term for
what is today usually called "IS" (information services what is today usually called "IS" (information services
or systems) or "MIS" (management information or systems) or "MIS" (management information
services or systems), is the processing of services or systems), is the processing of datadata by a by a
computer and its programs in an environment computer and its programs in an environment
involving electronic communication. EDP evolved from involving electronic communication. EDP evolved from
"DP" (data processing), a term that was created when "DP" (data processing), a term that was created when
most computing input was physically put into the most computing input was physically put into the
computer in punched card form or in ATM cards computer in punched card form or in ATM cards
form and output as punched cards or paper reports.form and output as punched cards or paper reports.

4. Real Time Processing
There is a continual input, process There is a continual input, process
and output of data. Data has to be processed in a and output of data. Data has to be processed in a
small stipulated time period (real time), otherwise it small stipulated time period (real time), otherwise it
will create problems for the system. will create problems for the system.
For exampleFor example, when a bank customer withdraws a sum , when a bank customer withdraws a sum
of money from his or her account it is vital that the of money from his or her account it is vital that the
transaction be processed and the account balance transaction be processed and the account balance
updated as soon as possible, allowing both the bank updated as soon as possible, allowing both the bank
and customer to keep track of funds.and customer to keep track of funds.

5. Batch Processing
In a batch processing group of transactions In a batch processing group of transactions
collected over a period of time is collected, entered, collected over a period of time is collected, entered,
processed and then the batch results are produced. processed and then the batch results are produced.
Batch processing requires seperate programs for Batch processing requires seperate programs for
input, process and output. It is an efficient way of input, process and output. It is an efficient way of
processing high volume of data. processing high volume of data.
